| 英文摘要 | Acidic silicon sol was prepared by ion exchange using na2sio3 center dot 9h(2)o as raw material. spherical sio2-al2o3 composites were prepared by oil-drop method after mixing of silicon sol, hexamethylenetetramine, and aluminium sol. the samples were characterized and analysized by xrd, bet, and tpd. the results showed that sio2 existed in sio2-al2o3 composites in amorphous phase and that specific surface area, pore volume, and surface acidity increase with the increase of sio2 content, accompanied with the decrease of average pore diameter and bulk density. the crash strength kept approximate constant. |
